A pupil swerves around a parked car without mirror checks while a motorcycle is close behind. What is the best instructor action if safety margins are being lost?

1. Let it continue so the pupil learns from the motorcycle's reaction
2. Intervene verbally or physically as needed to keep everyone safe, then debrief the observation failure
3. Praise the pupil for avoiding the parked car quickly
4. Focus only on whether the pupil signalled
